摘要： A simulation method predicts wet spreading and unions of a plurality of droplets arranged on a patterned surface defined by a fine pattern of protrusions and recesses, the patterned surface causing anisotropy to occur in the wet spreading of the droplets. The influence imparted by the pattern of protrusions and recesses that defines the patterned surface, which is the target of analysis, on the wet spreading of the droplets is treated as wetting properties of an analysis surface, and the wet spreading and unions of the plurality of droplets on the analysis surface are analyzed by gas liquid two phase flow analysis that incorporates the wetting property parameters that represents the wetting properties.

摘要： Provided are a printing plate, a method for manufacturing a printing plate, and a printing method that allow for high-resolution printing and efficient use of printing ink. The printing plate has an image area and a non-image area. The image area is formed by a layer containing silicone rubber. The non-image area is formed by a layer containing a fluorine compound on a surface of the layer containing silicone rubber. The height difference between a surface of the image area and a surface of the non-image area is 100 nm or less. The method for manufacturing a printing plate has the steps of subjecting a region of a surface of a layer containing silicone rubber to chemical treatment or physical treatment to form hydroxyl groups, the region being a region that becomes a non-image area; and binding a fluorine compound to the region, having the hydroxyl groups formed thereon, of the surface of the layer containing silicone rubber to form a non-image area. The printing method has an ink-applying step of applying a printing ink to an image area and a transfer step of transferring the printing ink from the image area to a substrate.
